Worlds turn simulation models into playable systems—with their own rules, communities and economies. Explore example launches, study the token design and build something entirely new.
These are launch concepts—not active offerings. Each shows how a model, token and community could fit together. Use them as a starting point, then make the idea yours.
Nations, alliances and finite resources collide across persistent campaigns.
Deploy units, form alliances and enter campaigns.
Community-owned marbles compete through a season of physics-driven events.
Enter events, customize racers and unlock formats.
Change ocean heat, pressure and wind—then watch new storm systems form.
Create scenarios, run forecasts and access datasets.
Competing lineages grow, mutate and fight across a finite cheese substrate.
Create cultures, trigger actions and enter seasons.
Every launch starts by defining what people do, why the system needs a token and how outcomes become trustworthy.
Build your launchUse a reusable Blueprint or build a custom simulation engine.
Define the actions, constraints and outcomes that make the World worth entering.
Connect utility to real actions—not a ticker in search of a reason.
Fund compute, preserve the rules and make important results auditable.
Bring the concept. Spawn helps shape the model, economics, runtime and launch structure.
